Diagnosing Jimmy Crute's UFC261 Injury 🥊

The video explores the anatomy of the leg, focusing on the sciatic nerve and its components, the common fibular and tibial nerves. It explains how these nerves control various muscles and their actions, such as plantar flexion and dorsiflexion. The video also discusses the balance of muscle actions and the impact of nerve damage, using Jimmy Crute's injury as a case study. The injury analysis highlights how damage to the common fibular nerve affects muscle function, leading to imbalances in dorsiflexion and eversion, and increasing the likelihood of ankle rolling.

What are the two nerves that make up the sciatic nerve?

• Common fibular nerve and tibial nerve

• Tibial nerve and sural nerve

• Femoral nerve and tibial nerve

• Common fibular nerve and femoral nerve

Which muscle is primarily responsible for plantar flexion?

• Tibialis anterior

• Gastrocnemius

• Fibularis longus

• Soleus

What action is the opposite of dorsiflexion?

• Inversion

• Eversion

• Plantar flexion

• Circumduction

What happens when the common fibular nerve is damaged?

• Enhanced eversion

• Increased dorsiflexion

• Unopposed plantar flexion

• Improved inversion

Which nerve controls the tibialis anterior muscle?

• Sural nerve

• Tibial nerve

• Deep fibular nerve

• Superficial fibular nerve

What compensatory action does Jimmy Crute use to clear his foot?

• Hip hiking

• Knee flexion

• Ankle inversion

• Toe curling

Why is Jimmy Crute more likely to roll his ankle after the injury?

• Improved inversion

• Enhanced plantar flexion

• Lack of eversion

• Increased dorsiflexion
